Hallo,
Im having problems with condensation in my newly rebuild ford 390! Im geting a thin white cream layer inide of my valv cover, the one with the pcv valve in it! Is this normal? Tried checking the block and heads for cracks when rebuilding it, but couldent see any!? Dident have any water in oil before rebuild! I have no water on the dipstick, and oil looks fresh in the pan! Looks like new..

I have had the intake and heads of, and changed the gaskets! But the problems remain!? Tried pressuretesting the coling system, but becouse of bad hoses i get a pressure/fluid leek there! Took it upp to 1,5 bar, and had it standing with pressure for a couple of hours with valve covers of ( pumped it upp when it got down to 1 - 0.5 bar) ,but couldent se any signs of coolant in engine!? Started the engine and warmed it upp, and still looks like new oil on dipstick!? Also had the coolant checked for exhaust gases, and no white smoke from tail pipes!

Would be very thankful for some input and idees, is this normal?! I dont take her on very long tripps, mayby half an hour or so, but its varm outside..

Thanks in advance! /Oskar
